Issue/Introduction

At Charter they are using deviceIPMaskList to get the subnet mask of the primary IPv4 IP.   This works fine for IPv4.  However, the entries for IPv6 have blank subnet masks

Here is an example of the attribute and the lack of IPv6 masks:

It looks to work like the following:

First number indicates whether it is IPv6 or IPv4:

 

16 – Ipv6

4 – ipV4

 

The next 16 digits represents the Address itself if ipv6 (indicated by the 16 above)

 

254: 0xFE

128: 0x80

 

0: 0x0

0: 0x0

 

0: 0x0

0: 0x0

 

0: 0x0

0: 0x0

 

42: 0x2A

138: 0x8A

 

28:  0x1C

255: 0xFF

 

254: 0xFE

195: 0xC3

 

170: 0xAA

193: 0xC1

 

 

Append these together for the following IPv6 Address:  FE80:0000:0000:0000:2A8A:1CFF:FEC3:AAC1


 

Environment

Release : 20.2

Component : Spectrum Core / SpectroSERVER

Resolution

This will be fixed in a future release of Spectrum.
